Wheels to prevent them from slipping and may be' operated by a footpedal.

Referring to the annexed drawing in which my inventionis illustrated andwhich forms a part of this specification:

Figure 1 is aside elevation of the rear portion of an automobile and mysanding device mounted thereon. i

Figure 2 is a top plan view of the running gear of said automobile andmy sanding device mounted thereon. I

Figure 8 a fragmentary bottom plan view of the rear portion of saidautomobile and my sanding device mounted thereon.

F igure 4c is a plan view of the sand-dolivery valve.

In the drawing 1 indicates a sand box which issuspended forwardly of therear axle 2 of the automobile on bars 3 extending transversely of theautomobile and secured on the automobile chassis l. From the ends of thebox 1 spouts 5 project downwardly in front of the rear Wheels 66 of theautomobile. In each spout 5 is mounted a sliding valve 7 on the innerend of which is formed a lip S for engaging" the wall of the spout toprevent the valve from being pulled out of the spout. Levers 99 arepivoted on the box 1, to one end of ".vhich are respectively pivoted theouter ends of the valves To the other end of said levers are connectedthe rear ends of rods 1010 re- 1922, Serial No. 562,659.

spectively extending longitudinally. of the automobile within thechassis 4, the forward ends of which rods being connected todepending-arms 1111 respectively secured on u a shaft 12 extendingtransversely of the forward part of the chassis 4t and journaled on theside members of said chassis. 13-13 are connected to the levers99.respectively and to the sand box 1 for normally holding the valves 77closed. A pedal 14 is secured to the shaft 12 at the left of theautomobile, which pedal may be depressed by the driver of the automobileto open the valves 77 through the medium of the levers 9-9, rods l010,arms 111l' and shaft 12,- so that sand will drop from the box 1 throughthe spouts 55 in front of the rear automobile wheels 6-6, whereby therear wheels are prevented from a slipping.
